More bullshit without all the facts. The two cases of popcorn lung were directly linked to the binding agent propylene glycol in one batch of "overseas" vape liquid. Now I'm not stupid enough to think that sucking any type of substance into your lung besides oxygen is ideal but it's one hell of a lot better that conventional combustion smoking.

Propylene glycol is a bog standard diluent for e-liquid, usually used in combination with vegetable glycerin. I don't know which country you're in but at least some of its domestic e-juice makers use PG for sure.
